Long Islanders and the rest of the nation are marking National Fishing Week, but gas prices have put a crimp in the celebrations.Rising fuel prices and new fishing regulations are taking their toll on boaters this year. Those who run charter fishing boats say they are now struggling to stay afloat.Boat captain George Bartenback says he needs 10 people to use his boat just to break even on any given day. On Thursday, he said he had 12, which is much less than his average of 20-25 people.Bartenback also says many customers are staying away due to new laws that require fish be thrown back into the water if they don't meet a certain length requirement.
